According to Lawrence Lessig, we now have two cultures on the Internet: the Read Only (RO), e.g., itunes; and the Read-Write (RW): blogs, Flickr, Linux, Wikipedia. Copyright law, however, likes RO and not RW.

Disclaimer: The presence of the US flag in the background was not intentional. And the words "weirdly totalitarian" on the screen behind Lessig was purely coincidental.
